  • Patent number: 8351801
    Abstract: An image forming apparatus has an image forming station for forming an image and a display unit for displaying specified information. A mode changing section switches a mode of the image forming apparatus between a first mode for waiting on standby with a first power consumption and a second mode for waiting on standby with second power consumption lower, than the first power consumption. A determining section determines whether an image can be formed after the mode is switched from the second mode to the first mode and a starting section starts the display unit when the determining section determines that no image can be formed. A notifying section generates a display on the display unit of information indicating that no image can be formed.

    Abstract: A method for printer stability enhancement in a multiple printer printing system includes determining a first printer stress state of a first printer in a printing system, wherein the first printer is assigned a first printing role. A second printer stress state of a second printer in the printing system is also determined, wherein the second printer is assigned a second printing role that is different from the first printing role. The first printer stress state is compared to the second printer stress state, and the first printing role is reassigned to the second printer and the second printing role is reassigned to the first printer if the first printer stress state is different than the second printer stress state. A printing system implementing the method is also provided.

  • Patent number: 8301041
    Abstract: A first power source unit supplies power to a first control unit accessing a storage unit. An image forming unit controlled by a second control unit is provided with a load for forming an image. A second power source unit supplies power to the load and the storage unit. A switch unit is operated to power on or off an image forming apparatus. The first control unit, upon receiving the status signal instructing power-off, causes the storage unit to shut down and transmits an instruction to cause the load to shut down to the second control unit. The second control unit, if a shutdown instruction is not received even when the status signal instructing power-off has been detected, performs control to stop the load and then stop the supply of power from the second power source unit.

  • Patent number: 8294918
    Abstract: An image forming apparatus includes a failure prediction unit, an image identification unit, a simulated-image generating unit, and an output unit. The failure prediction unit prepares an index value indicating a condition of the image forming apparatus based on multidimensional signal, obtained by monitoring the image forming apparatus, and compares the index value with a first threshold value to predict a failure mode of the image forming apparatus. The image identification unit identifies types of abnormal images based on the failure mode predicted by the failure prediction unit. An identified abnormal image is predicted to be appear a given time later. The simulated-image generating unit generates a simulated image of the identified abnormal image. The output unit outputs the identified abnormal image as the simulated image.
